Is it possible to verify if the system has a DVD burner installed? I need this for a script.
As said in a comment, there is a cleaner way of doing that:
wodim -prcap which gives exactly what you need.
Device seems to be: Generic mmc2 DVD-R/DVD-RW.
dmesg | grep RW, in my case (DVD-RW/BD reader drive) it returns something like
[ 2.399074] ata2.00: ATAPI: HL-DT-ST DVDRW/BDROM CT40N, A101, max UDMA/133 [ 2.409247] scsi 1:0:0:0: CD-ROM HL-DT-ST DVDRWBD CT40N A101 PQ: 0 ANSI: 5
wodim dev=/dev/cdrom -scanbus:
