Systemd-tools is conflicted with udev

[geeeeeee]

I use pink Pogo.

Recently, I have upgrade pacman package and got this message

There are some inter-confilcts between systemd-tools and udev,
so I have to remove udev-oxnas.

but, I have read that udev-oxnas is essential package to avoid be a brick pogo after reboot.

So, I try to re-install udev-oxnas, but I can't.
$this->bbcode_second_pass_code('', '
[root@alarm ~]# pacman -Sf udev-oxnas
resolving dependencies...
looking for inter-conflicts...
:: udev-oxnas and systemd-tools are in conflict (udev). Remove systemd-tools? [y/N] n
error: unresolvable package conflicts detected
error: failed to prepare transaction (conflicting dependencies)
:: udev-oxnas and systemd-tools are in conflict
')

and I try to remove systemd-tools, but I got this message.

$this->bbcode_second_pass_code('', '
[root@alarm ~]# pacman -Sf udev-oxnas
resolving dependencies...
looking for inter-conflicts...
:: udev-oxnas and systemd-tools are in conflict (udev). Remove systemd-tools? [y/N] y
error: failed to prepare transaction (could not satisfy dependencies)
:: mkinitcpio: requires systemd-tools
')

so, I'm afraid of to reboot my pogo plug. I think it will be a bricked pogo after reboot.
Is there any solution to re-install udev-oxnas?
or Is it ok to reboot my pogo plug?
