I use ksh, HISTSIZE=32767, .sh_history not in volatile /tmp, and periodically I make a gzipped backup that my command search scripts can look in to expand my ksh typein history. Then I use command-line stuff where I can, since I will have history, rather than long sessions. For instance, in place of hangin around as root where I might accidentally do something destructive, and having my session uistory be up there on root, I call it on this shell history like this:
Code:
su - root -c 'little command sequence'

systemd-volatile-root.service

SYSTEMD-VOLATILE-ROOT.SERVICE(8)			   systemd-volatile-root.service			  SYSTEMD-VOLATILE-ROOT.SERVICE(8)

NAME

       systemd-volatile-root.service, systemd-volatile-root - Make the root file system volatile

SYNOPSIS

       systemd-volatile-root.service

       /lib/systemd/systemd-volatile-root

DESCRIPTION

       systemd-volatile-root.service is a service that replaces the root directory with a volatile memory file system ("tmpfs"), mounting the
       original (non-volatile) /usr inside it read-only. This way, vendor data from /usr is available as usual, but all configuration data in
       /etc, all state data in /var and all other resources stored directly under the root directory are reset on boot and lost at shutdown,
       enabling fully stateless systems.

       This service is only enabled if full volatile mode is selected, for example by specifying "systemd.volatile=yes" on the kernel command
       line. This service runs only in the initial RAM disk ("initrd"), before the system transitions to the host's root directory. Note that this
       service is not used if "systemd.volatile=state" is used, as in that mode the root directory is non-volatile.
