Re: [aclug-L] BRAND SPANKIN' NEW HDD!!!!!!!!!

[John Goerzen <jgoerzen@xxxxxxxxxxxx>]

I disagree with this, myself.  I reccommend one large partiion only if 
your disk is less than somewhere between 500 meg and 1 gig.

The benefits of multiple partitions are:
 * Easier migration between OSs, esp. between distributions
   (ie, if /home is on a separate partition, things become very easy)

 * If a vital system area of one partition is corrupted, you do not
   lose all data -- only the data on that particular partition.

 * Filesystem checks can be faster if you have to check only one small
   partition instead of one large partition.

Also, if you ever do find out that you are running out of space on one 
particular partition, symlinks can quickly solve the problem.

In short, while there may not be immediate advantages, there are
definite advantages down the road to using separate partitions.
