Re: Why should "/boot" be on a separate partition?



The only good reason I have ever seen for this is as a work around for
broken bioses that are limited in how far into the disk they can see
in order to read the boot blocks. A small partition near the front of
the drive ensures that any blocks allocated to the boot file are
reachable - and once the kernel is in memory you are using more capable
Unix/Linux drivers which are unrestricted and hence can access the root
partition wherever it lies..

I have heard some people try to justify it on security/safety grounds - ie
if your boot file is normally unmounted or mounted read-only, you are less
likely to damage it. But boot files are easily recreated so I see no reason
to be overly anal about such things. I am much more concerned about being
cautious with configuration files and user files.

Personally I prefer to keep a small root filesystem which can be backed up
regularly, with separate partitions for /usr, /home, /var etc. I see no
need to a separate /boot partition under this scenario, and it was certainly
not standard practice on traditional Unix systems.

Assuming you are going to have a separate root for Ubuntu and Debian, there
doesn't seem to be any reason to keep the boot files together - but it can
be done if you really want to.
