Package: extlinux
Version: 2:4.03+dfsg-9
Severity: important
Tags: experimental patch
Hi,
on one system I have my / partition (including /boot) on /dev/sda3. The
extlinux-update script thus correctly sets the EXTLINUX_ROOT variable to
/dev/sda3, resp. its UID. However, when the root partition is represented by
its UID in EXTLINUX_ROOT, then extlinux-postinst will call extlinux-install
with this UID, i.e. "extlinux-install ${UID-of-/dev/sda3}" instead of
"extlinux-install ${UID-of-/dev/sda}". Needless to say this won't install
/usr/lib/extlinux/mbr.bin into the MBR of the /dev/sda disk.
I think the UUID of the root partition has to get translated into the classic
device name form and then get the partition number removed. the attached patch
does right this.
