<title>Make Root Filesystem Writable</title>
|
||
|
|
<p>Sometimes it can be useful to make changes directly to the citadel root filesystem to
|
||
|
|
experiment with changes or to debug a problem.</p>
|
||
|
|
<p>First <code>citadel.noverity</code> must be added to the kernel commandline. After booting with
|
||
|
|
this command line option verify that dm-verity has been disabled with the <code>dmsetup</code>
|
||
|
|
command.</p>
|
||
|
|
<screen># dmsetup status rootfs
|
||
|
|
0 4194304 linear</screen>
|
||
|
|
<p>If the output displays <code>verity</code> instead of <code>linear</code> then dm-verity is enabled
|
||
|
|
and the disk cannot be safely written to.</p>
|
||
|
|
<p>Next remount the root filesystem with read-write flag.</p>
|
||
|
|
<screen># mount -oremount,rw,noatime /</screen>
