Hello!
While customizing my ifiles installation, some ideas popped into my mind I
want to share with you and about which I'd like to read your comments.
I'd like to introduce a virtual service that marks the earliest point at
which the bare system is usable (i.e., a root login is possible). The would
be similar to the rc.S script in a sysv environment. Other services and
daemons could depend on this virtual service. This would (a) clarify
the "the system is now more or less up" point we now implicitly mark with
system/bootmisc (which is, in my opinion, not a good style), and it (b)
could speed up the boot process a little more, because services that are
not that important for a system initialization could be started more in
parallel with daemons.
Important for the bare system are udev, lvm/raid configuration, (local)
networking (see below), mountfs, clock (because sometimes, when the clock
service is run to late, I encountered that DHCP stopped working because the
PID file had a modification time in the future) and getty.
I'd suggest "virtual/basesys", "virtual/sysinit" or something similar for
this.
At the moment, we have a virtual/net service. However, when setting up NFS
environments (for /home and /usr), I found that virtual/net is called to
late. I'd like to split it up into virtual/lan und virtual/wan (virtual/net
may depend on both). "virtual/lan" would include static ethernet
configurations and DHCP, while virtual/wan would be for PPP, PPPoE and
others.
The goal is to divide networking into a part that must be present early in
the boot process for NFS and the like, and other networking services that
are not so important for the bare system, like an internet connection made
via the pppd. But a firewall script could continue to rely on virtual/net,
thus having both eth0 and ppp0 present for the iptables setup.
These ideas are rather raw; I'm looking forward to your comments and
suggestions.
Eric
