Subject: xfs: add debian initramfs hook to package
X-Git-Tag: v4.18.0-rc1~3
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=900bd62e51fbb13db96cffb11f5504e3eec217ac;p=thirdparty%2Fxfsprogs-dev.git

xfs: add debian initramfs hook to package

In Debian bug 904086, the reporter complained that xfs_repair wasn't
present in the initramfs, which prevented him from using shutdown -F to
force a filesystem fsck after a reboot.  Add a hook to put the xfs
utilities in the initramfs if xfs is the root filesystem.
