[SlugBug] Appending to Crontab ?

[Alan Dawson]

Hi .. 

I've got a number of similar tasks that need to be done from cron whenever a new
site is added.

the cron tasks are already set out in a file called 

/srv/site-1/cron/crontab.in
/srv/site-2/cron/crontab.in
..

but when i go 

crontab -u site-process /srv/site-1/cron/crontab.in
crontab -u site-process /srv/site-2/cron/crontab.in

the second line wipes out the crons from the first

Is there a way to append to a crontab from script ?  

cheers
