Anybody know why my fstab is getting overwritten, or how I can accomplish this task?

Note: I don't have any trouble accessing SMB shares, I'm just trying to map some shares into my home directory for easy access. In fact, the workaround is just to copy up a new fstab and then mount the shares, works perfectly. It just seems like a rather grubby workaround. On most Linux installs, one just edits fstab to map the shares, and then it's done for good.

@applee Well, that's a good point. fstab is probably not doing anything besides automatically mounting shares that could as easily be dynamically mounted by a script. smbmount seems to be obsolete but it looks like one can do it with mount.cifs in just the same way as with fstab. I'll work that out and report back.
