[PATCH] recipes-support: add fsck to initramfs

[PATCH] recipes-support: add fsck to initramfs

[Q. Gylstorff]

From: Quirin Gylstorff <quirin.gylstorff@siemens.com>

During system start it shall be possible to check all available file systems.
As debootstrap has no knowledge of the existing file system it will not add all fsck.*
application necessary to the initramfs.
This patch adds all file system types given by IMAGE_FILESYSTEM_TYPES to the initramfs.

File system types in IMAGE_FILESYSTEM_TYPES are separated with spaces.

Re: [PATCH] recipes-support: add fsck to initramfs

[Henning Schild]

Well it looks like the problem is the missing fstab
line. /usr/share/initramfs-tools/hooks/fsck is looking for that to
decide which fsck to include.

There also seems to be /etc/fstab.d/*.fstab that can be used if we do
not like touching the original fstab. I think Claudius once removed /
from fstab claiming that it was not required.

The package you get from that changes content based on an image
variable. That must not be done. The fstypes would have to become part
of PN or PV ...

I think we should get that fstab line back.

/ is in fstab, but in a generic form. If you add a specific one, you easily 
start duplicating wic. It's a chicken-egg thing: You need the information during 
package installation, but you only have it after imaging.

BTW, there is enable-fsck for partially the same reason (there other is that you 
do want to control whether fsck is run in embedded scenarios).

No, i have not touched the /etc/fstab generation code. That code goes
all the way back, when multistrap was used and the fstab was generated
in the config scripts. I thought about refactoring that and put the idea
out, but I never did.

Claudius

Fair enough. Let is control which fscks go into the initrd. But i am
afraid we will need one package per file-system. I guess that should be
easy to do with one recipe providing many packages.
And which ones to include would be a matter of

IMAGE_INSTALL += <initrd-fsck-package>-<fstype>

And not a new variable.

At least that sounds like a viable way to implement it.

[PATCH v2] recipes-support: add fsck to initramfs

[Q. Gylstorff]

From: Quirin Gylstorff <quirin.gylstorff@siemens.com>

During system start it shall be possible to check all available file systems.
As debootstrap has no knowledge of the existing file system it will not add all fsck.*
application necessary to the initramfs.
