Bug#508834: grub-probe is painfully slow to execute due to excessive ioctl(BLKFLSBUF)

[Michal Suchanek]

Package: grub-pc
Version: 1.97~beta3-1
Severity: normal


I must say that update-grub preformance is much worse in grub-pc than
grub legacy so compared to grub-legacy this is a regression.

For me update-grub is not running 10 minutes so it is not a critical
problem but it is still run quite a few times during kernel
install/upgrade/removal.

Optimizing this or the number of invocations of update-grub by debconf
is probably desirable.

Thanks

Michal
