Hallo; when I update a factory installation chrooted by running the following script I see grub2-mount processes hanging around with 100% CPU for some minutes. Am I doing something wrong ? Or is this a bug in grub2-mount ?

Quite possible. Could you strace it?

How do I attach strace to a grub2-mount process, which isn't started manually, but probably by one of the installation scripts run by rpm/zypper ? I can't start it manually because I don't know the parameters ( like image or mountpoint) which are used for grub2-mount in that installation script. -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-factory+owner@opensuse.org

I can't start it manually because I don't know the parameters ( like image or mountpoint) which are used for grub2-mount in that installation script. This is a end of a grub2-mount strace output. There are a lot more read/lseek and break calls at the begin, but since I missed the start of the grub2-mount I don't have more relevant info about what it is trying to do.

How do I attach strace to a grub2-mount process, which isn't started manually, but probably by one of the installation scripts run by rpm/zypper ?

It could be done by stracing zypper and all children (with a separate log file per PID) - but that would be a lot. But my guess is that it is os-prober, so simply disable it in grub config. -- Cheers / Saludos, Carlos E. R. (from 13.1 x86_64 "Bottle" at Telcontar)
