Subject: poudriere jail update from source: syscall.mk does not exist

After updating to yesterday's aba921bd9e1869dae9ae4cc6e0c048f997401034, I aimed for a routine update of the jail that I used for poudriere.

poudriere jail -u -J 1 -j main
…
===> lib/libc (install)

make[5]: Fatal errors encountered -- cannot continue

bdrewery and others in IRC helped me to realise an offending mount.


With linux_enable: YES,

root@mowa219-gjp4-8570p-freebsd:~ # mount | grep sys
linsysfs on /usr/src/sys (linsysfs, local)
root@mowa219-gjp4-8570p-freebsd:~ # exit
logout
% grep linsysfs /etc/fstab

%


After linux_enable: NO and a reboot,

% sysrc -f /etc/rc.conf linux_enable
linux_enable: NO
% mount | grep sys
% date ; uname -aKU

% sudo sysrc linux_enable="YES"
