Bug 7351 – On x86 platform, given /etc/fstab is impossible

• Product: [OLD] Docs-user
• Status: RESOLVED FIXED

[Description Evan Read 2002-09-01 17:27:44 UTC]

The given /etc/fstab in the security documentation is impossible to replicate on the x86 plaform (and maybe  
others)?  
  
The given /etc/fstab/:  
 
<begin fstab>  
/dev/sda1 /boot ext2 noauto,noatime 1 1 
/dev/sda2 none swap sw 0 0 
/dev/sda3 / reiserfs notail,noatime 0 0 
/dev/sda4 /tmp reiserfs notail,noatime,nodev,nosuid,noexec 0 0 
/dev/sda5 /var reiserfs notail,noatime,nodev 0 0 
/dev/sda6 /home reiserfs notail,noatime,nodev,nosuid 0 0 
/dev/sda7 /usr reiserfs notail,noatime,nodev,ro 0 0 
/dev/cdroms /cdrom0 /mnt/cdrom iso9660 noauto,ro 0 0 
proc /proc proc defaults 0 0 
</end fstab> 
 
Partitioning 7 partitions in a row is impossible on x86 (starting from 1).  One of these partitions (most likely 
4) needs to be an extended partition for the rest and therefore cannot be directly assigned like that.  A more 
likely scenario is this: 
 
<begin fstab> 
/dev/sda1 /boot ext2 noauto,noatime 1 1 
/dev/sda2 none swap sw 0 0 
/dev/sda3 / reiserfs notail,noatime 0 0 
# parition four is container for subsequent partitions 
/dev/sda5 /tmp reiserfs notail,noatime,nodev,nosuid,noexec 0 0 
/dev/sda6 /var reiserfs notail,noatime,nodev 0 0 
/dev/sda7 /home reiserfs notail,noatime,nodev,nosuid 0 0 
/dev/sda8 /usr reiserfs notail,noatime,nodev,ro 0 0 
/dev/cdroms /cdrom0 /mnt/cdrom iso9660 noauto,ro 0 0 
proc /proc proc defaults 0 0 
</end fstab> 
 
In the case where this limitation doesn't exist on other platforms, it might be worthwhile putting fstabs in for 
all platforms.  
 
This is the paritioning scheme I use and is proven to be correct (ie what fdisk will let you do). 
 
Thanks! 
 
Evan.

I fixed this and commented it appropriately.
