#297 closed defect (fixed)

syslinux doesn't seem to work through NFS

Description (last modified by Bruno Cornec)

When using mondoarchive through NFS for -T and -S, mindi is called with temp files created through NFS as well.

syslinux called in mindi then hang (Status D) as here: 

root     30894  0.0  0.0  2612  604 pts/4    D+   19:11   0:00 mattrib -h -r -s s:ldlinux.sys

A workaround in mindi consist in launching syslinux on a local disk before copying it on NFS.

mindi 2.0.4 line 1692:

Change 

        syslinux $imagefile >> $LOGFILE 2>> $LOGFILE

into 

        mv $imagefile /tmp/$imagefile
        syslinux /tmp/$imagefile >> $LOGFILE 2>> $LOGFILE
        mv /tmp/$imagefile $imagefile

A workaround is to not use NFS for scratch
