AutoYAST and custom swap partitioning

Well, we’ve been discussing our swap partitioning the last few days at work, and I finally got around to implementing it. Again, it proved to be kinda hard, basically because AutoYAST decides to do things differently. After trying different things, I came up with this:

		&lt;rule&gt;
			&lt;memsize&gt;
				&lt;match&gt;32767&lt;/match&gt;
				&lt;match_type&gt;greater&lt;/match_type&gt;
			&lt;/memsize&gt;
			&lt;result&gt;
				&lt;profile&gt;system/swap/32G.xml&lt;/profile&gt;
				&lt;continue config:type=&quot;boolean&quot;&gt;false&lt;/continue&gt;
				&lt;dont_merge config:type=&quot;list&quot;&gt;
					&lt;element&gt;partition&lt;/element&gt;
				&lt;/dont_merge&gt;
			&lt;/result&gt;
		&lt;/rule&gt;

		&lt;rule&gt;
			&lt;memsize&gt;
				&lt;match&gt;16383&lt;/match&gt;
				&lt;match_type&gt;greater&lt;/match_type&gt;
			&lt;/memsize&gt;
			&lt;result&gt;
				&lt;profile&gt;system/swap/16G.xml&lt;/profile&gt;
				&lt;continue config:type=&quot;boolean&quot;&gt;false&lt;/continue&gt;
				&lt;dont_merge config:type=&quot;list&quot;&gt;
					&lt;element&gt;partition&lt;/element&gt;
				&lt;/dont_merge&gt;
			&lt;/result&gt;
		&lt;/rule&gt;

		&lt;rule&gt;
			&lt;memsize&gt;
				&lt;match&gt;8191&lt;/match&gt;
				&lt;match_type&gt;greater&lt;/match_type&gt;
			&lt;/memsize&gt;
			&lt;result&gt;
				&lt;profile&gt;system/swap/8G.xml&lt;/profile&gt;
				&lt;continue config:type=&quot;boolean&quot;&gt;false&lt;/continue&gt;
				&lt;dont_merge config:type=&quot;list&quot;&gt;
					&lt;element&gt;partition&lt;/element&gt;
				&lt;/dont_merge&gt;
			&lt;/result&gt;
		&lt;/rule&gt;

		&lt;rule&gt;
			&lt;memsize&gt;
				&lt;match&gt;4095&lt;/match&gt;
				&lt;match_type&gt;greater&lt;/match_type&gt;
			&lt;/memsize&gt;
			&lt;result&gt;
				&lt;profile&gt;system/swap/4G.xml&lt;/profile&gt;
				&lt;continue config:type=&quot;boolean&quot;&gt;false&lt;/continue&gt;
				&lt;dont_merge config:type=&quot;list&quot;&gt;
					&lt;element&gt;partition&lt;/element&gt;
				&lt;/dont_merge&gt;
			&lt;/result&gt;
		&lt;/rule&gt;

		&lt;rule&gt;
			&lt;memsize&gt;
				&lt;match&gt;2047&lt;/match&gt;
				&lt;match_type&gt;greater&lt;/match_type&gt;
			&lt;/memsize&gt;
			&lt;result&gt;
				&lt;profile&gt;system/swap/2G.xml&lt;/profile&gt;
				&lt;continue config:type=&quot;boolean&quot;&gt;false&lt;/continue&gt;
				&lt;dont_merge config:type=&quot;list&quot;&gt;
					&lt;element&gt;partition&lt;/element&gt;
				&lt;/dont_merge&gt;
			&lt;/result&gt;
		&lt;/rule&gt;

		&lt;rule&gt;
			&lt;memsize&gt;
				&lt;match&gt;1023&lt;/match&gt;
				&lt;match_type&gt;greater&lt;/match_type&gt;
			&lt;/memsize&gt;
			&lt;result&gt;
				&lt;profile&gt;system/swap/1G.xml&lt;/profile&gt;
				&lt;continue config:type=&quot;boolean&quot;&gt;false&lt;/continue&gt;
				&lt;dont_merge config:type=&quot;list&quot;&gt;
					&lt;element&gt;partition&lt;/element&gt;
				&lt;/dont_merge&gt;
			&lt;/result&gt;
		&lt;/rule&gt;

		&lt;rule&gt;
			&lt;memsize&gt;
				&lt;match&gt;1023&lt;/match&gt;
				&lt;match_type&gt;lower&lt;/match_type&gt;
			&lt;/memsize&gt;
			&lt;result&gt;
				&lt;profile&gt;system/swap/default.xml&lt;/profile&gt;
				&lt;continue config:type=&quot;boolean&quot;&gt;false&lt;/continue&gt;
				&lt;dont_merge config:type=&quot;list&quot;&gt;
					&lt;element&gt;partition&lt;/element&gt;
				&lt;/dont_merge&gt;
			&lt;/result&gt;
		&lt;/rule&gt;

<rule>

<match_type>greater</match_type>

</memsize>

<profile>system/swap/32G.xml</profile>

<continue config:type="boolean">false</continue>

<dont_merge config:type="list">

</dont_merge>

</result>

</rule>

<rule>

<continue config:type="boolean">false</continue>

<dont_merge config:type="list">

</rule>

The content of a profile looks like this:

	&lt;partitioning config:type=&quot;list&quot;&gt;
		&lt;drive&gt;
			&lt;partitions config:type=&quot;list&quot;&gt;
				&lt;partition&gt;
					&lt;create config:type=&quot;boolean&quot;&gt;true&lt;/create&gt;
					&lt;crypt_fs config:type=&quot;boolean&quot;&gt;false&lt;/crypt_fs&gt;
					&lt;filesystem config:type=&quot;symbol&quot;&gt;swap&lt;/filesystem&gt;
					&lt;filesystem_id config:type=&quot;integer&quot;&gt;130&lt;/filesystem_id&gt;
					&lt;format config:type=&quot;boolean&quot;&gt;true&lt;/format&gt;
					&lt;loop_fs config:type=&quot;boolean&quot;&gt;false&lt;/loop_fs&gt;
					&lt;mount&gt;swap&lt;/mount&gt;
					&lt;mountby config:type=&quot;symbol&quot;&gt;device&lt;/mountby&gt;
					&lt;partition_id config:type=&quot;integer&quot;&gt;130&lt;/partition_id&gt;
					&lt;partition_nr config:type=&quot;integer&quot;&gt;2&lt;/partition_nr&gt;
					&lt;resize config:type=&quot;boolean&quot;&gt;false&lt;/resize&gt;
					&lt;size&gt;16G&lt;/size&gt;
				&lt;/partition&gt;
			&lt;/partitions&gt;
		&lt;/drive&gt;
	&lt;/partitioning&gt;

<drive>

<crypt_fs config:type="boolean">false</crypt_fs>

<filesystem_id config:type="integer">130</filesystem_id>

<loop_fs config:type="boolean">false</loop_fs>

<mountby config:type="symbol">device</mountby>

<partition_id config:type="integer">130</partition_id>

<partition_nr config:type="integer">2</partition_nr>

<resize config:type="boolean">false</resize>

</partition>

</partitions>

</drive>

</partitioning>

So basically what I did, was creating different classes, and depending on the size of the available RAM, AutoYAST selects the profile.

S	M	T	W	T	F	S
		1	2	3	4	5
6	7	8	9	10	11	12
13	14	15	16	17	18	19
20	21	22	23	24	25	26
27	28	29	30
