wsrep-recover fails in mysqld_safe, Ubuntu (dash)

[Dane Miller]

The mysqld_safe script in PXC 5.5.28 fails to recover the galera replication position (--wsrep-recover) on Ubuntu 10.04 x86_64. I believe this is because Ubuntu links /bin/sh to the dash shell (https://wiki.ubuntu.com/DashAsBinSh), and dash does not support the $EUID variable used here:

# grep -n EUID /usr/bin/mysqld_safe
192: [ "$EUID" = "0" ] && chown $user $wr_logfile

The problem is fixed if I change mysqld_safe to use /bin/bash, instead of /bin/sh, or if I use `id -u` instead of "$EUID"

I am running...
