I'm setting up autoyast for autoinstall of Xen DomUs.
Both Xen Host & Guests run Opensuse Leap 42.2.
>From my Dom0 I pass pre-formatted, but not yet populated, LVMs as disks to the
>DomU config
guest.cfg
...
disk = [ 'phy:/dev/VG0/EFI,xvda,w','phy:/dev/VG0/ROOT,xvde,w']
...
I want my Guest /etc/fstab to end up as
UUID=AAAA-BBBB /boot/efi vfat [ ... efi fstab options ... ] 0 2
UUID=111...111 / ext4 [ ... root fstab options ... ] 1 1
proc /proc proc defaults 0 0
sysfs /sys sysfs noauto 0 0
debugfs /sys/kernel/debug debugfs noauto 0 0
devpts /dev/pts devpts mode=0620,gid=5 0 0
My question is how 'best' to set the 'proc', 'sysfs', debugfs', 'devpts' mounts
& their respective fstopts?
In the autoyast.xml that'll get passed to the xen.cfg, IIUC, I can use
<partitioning> for the passed-in devices, with 'initialize', 'create' &
'format' all == "false",
<partitioning config:type="list">
<drive>
<device>/dev/xvda</device>
<initialize config:type="boolean">false</initialize>
<partitions config:type="list">
<partition>
<create config:type="boolean"
>false</create>
<format
config:type="boolean">false</format>
<mount>/boot/efi</mount>
<mountby
config:type="symbol">uuid</mountby>
<fstopt>[ ... efi fstab options ...
]</fstopt>
<size>max</size>
<filesystem
config:type="symbol">vfat</filesystem>
<partition_nr
config:type="integer">1</partition_nr>
</partition>
</partitions>
</drive>
<drive>
<device>/dev/xvde</device>
<initialize config:type="boolean">false</initialize>
<partitions config:type="list">
<partition>
<create config:type="boolean"
>false</create>
<format
config:type="boolean">false</format>
<mount>/</mount>
<mountby
config:type="symbol">uuid</mountby>
<fstopt>[ ... root fstab options ...
]</fstopt>
<size>max</size>
<filesystem
config:type="symbol">ext4</filesystem>
<partition_nr
config:type="integer">1</partition_nr>
</partition>
</partitions>
</drive>
</partitioning>
Where in that case would I set the 'proc', 'sysfs', debugfs', & 'devpts'
mounts? They're not *additional* partitions, and from the docs, for a given
partition I can only have one <mount>...</mount>.
One option would be to use a postpartitioning script
<scripts>
<postpartitioning-scripts config:type="list">
<script>
cat EOF >> /etc/fstab
( ... fstab entries for 'proc', 'sysfs', debugfs', &
'devpts' ... )
EOF
</script>
</postpartitioning-scripts>
</scripts>
, modifying the just-created-fstab immediately after the <partitioning> step.
That's doable, but seems messy.
What's the recommended way to get to a completely defined fstab in the
Xen-DomU-install case above?
