MKISOFSRC may be used to point the program to a mkisofs startup file.

SOURCE_DATE_EPOCH belongs to the specs of reproducible-builds.org.
It is supposed to be either undefined or to contain a decimal number
which tells the seconds since january 1st 1970. If it contains a number,
then it is used as time value to set the default of --modification-date=,
--gpt_disk_guid, and --set_all_file_dates.
Startup files and program options can override the effect of SOURCE_DATE_EPOCH.
