Remember the better pull request article

A bookmark is just not enough, sometimes. And I have way to much of them anyway.

Ok. This is my flotsam & jetsam of the week:

The piece of cake is in the comment of Erik van Zijst:

git merge-tree `git merge-base master bob/master` master bob/master

Booting Linux on a server when filesystem is readonly

If your root server hoster loves to integrate 10 year old harddisks with a history of 89 previous customers you’ll have to cope many times with disk failures. If you launch a shutdown -r now or reboot you’ll likely see Input/output error messages and nothing more.

How to boot? You might use your IPMI interface or some kind of hosters panel. If this is not available for any reason here’s how you might be able to force booting immediately:

# echo 1 > /proc/sys/kernel/sysrq
# echo b > /proc/sysrq-trigger

This works (as root) because you can trigger the Magic_SysRq_key concept also via the proc filesystem.
