Bug#513216: /usr/sbin/grub-install: line 374: [: =: unary operator expected

[Thomas Lange]

Package: grub
Version: 0.97-47lenny2
Severity: normal

When I use grub-install for a chroot environment (during an
installation with FAI) I get following error:


# /usr/sbin/grub-install --no-floppy --root-directory=/target /dev/sda
grub-probe: error: Cannot open `/boot/grub/device.map'
/usr/sbin/grub-install: line 374: [: =: unary operator expected
Installation finished. No error reported.
This is the contents of the device map /target/boot/grub/device.map.
Check if this is correct or not. If any of the lines is incorrect,
fix it and re-run the script `grub-install'.

(hd0)   /dev/sda


This command is run form a nfsroot (which does no have a device.map),
the new system is located in /target on /dev/sda, were I like to
install the grub. grub-install is now checking which type of file
system I had created. This is a part of sh -x output of the command above:

+ sync
++ grub-probe -t fs /target/boot/grub
grub-probe: error: Cannot open `/boot/grub/device.map'
+ '[' = xfs ']'
/usr/sbin/grub-install: line 374: [: =: unary operator expected


I think this grub-probe should be called in this way:

grub-probe --device-map=/target/boot/grub/device.map -t fs /target/boot/grub 
which will report ext2 in my situation.
