[csw-users] Selecting 32 or 64 MySQL server

[Laurent Blume]

Sorry, the first had a copy/paste mistake, but actually, it can be much 
reduced:

# Get the default config
. /etc/opt/csw/csw.conf
# Get the specific config
. /etc/opt/csw/mysql5rc

# If MYSQLD_ARCH is set to something, use that
# architecture name

MYSQLD_SAFE=${BINDIR}/${MYSQLD_ARCH}/mysqld_safe


After all, if the variable is empty, // is not very elegant, but 
perfectly valid :-)

Or if keeping the if clause:

[...]
   # Else just use the minimal 32-bit default
   MYSQLD_SAFE=${BINDIR}/mysqld_safe
[...]
