Title. Asides from setting the whole disk to read-only. (It's not an option since apparently docker dislikes that for some reason.). I'm trying to increase my microsd's lifespan.

For instance, here's my current /etc/fstab

tmpfs /tmp tmpfs rw,size=10M,nr_inodes=5k,noexec,nodev,nosuid,uid=gus,gid=notgus,noatime,mode=1700

tmpfs /var/log tmpfs rw,size=10M,nr_inodes=5k,noexec,nodev,nosuid,uid=gus,gid=notgus,noatime,mode=1700

tmpfs /var/tmp tmpfs rw,size=0M,nr_inodes=5k,noexec,nodev,nosuid,uid=gus,gid=notgus,noatime,mode=1700

tmpfs /var/run tmpfs rw,size=0M,nr_inodes=5k,noexec,nodev,nosuid,uid=gus,gid=notgus,noatime,mode=1700

tmpfs /var/spool tmpfs rw,size=0M,nr_inodes=5k,noexec,nodev,nosuid,uid=gus,gid=notgus,noatime,mode=1700

tmpfs /var/lock tmpfs rw,size=0M,nr_inodes=5k,noexec,nodev,nosuid,uid=gus,gid=notgus,noatime,mode=1700

tmpfs /var/cache tmpfs rw,size=0M,nr_inodes=5k,noexec,nodev,nosuid,uid=gus,gid=notgus,noatime,mode=1700

Thanks in advance.
